. SHOE MACHINE.

.Application filed February 27, 1.919. Serial-No. 279,496.

To all whom it may concern-.-

Be it known that I, ALBERTF. FROUsSARD, a citizen ofthe'United- States of America, residing-at the city of St. Louis, State of Missouri, United States of America, have invented a certain new and-useful Shoe Machine, of which the following is such a-tull, clear, and exactdescription as will-enable any one skilled intheart to which itappertains to make and use the same, reference being had tothe accompanying drawings, forming part or" this specification.

My invention relates to a shoe'machine and more particularly toa machine 'for enclosing the toe, for pressing the :inturned llangeof the upper, and tor 'iorming the box toe of a' shoe.

In the accompanying drawings which illustrate one form of machine made in accordance with my invention, Fig. 1 is a side elevation 01": the complete machine, Fig. 2 is a tront'elevat-ioma portion of the last support being broken away, Fig. 3-is an enlarged detail view of the jaw slide, the cover plate being removedyFig. 4is a view similar to Fig. 3 but-showing the parts in diii'erent position, Fig. 5 is a front view o't'the box toe forming mold, Fig. 6 is a top'plan View ofthepartsshown in Fig. 2, Fig. 7 is a vertical-longitudinal section of the upper part of themachine, Fig. 8 is a section taken on theline 88 of Fig. 7 and Fig. 9 is a section taken on theline 9--9 of Fig. 7.

10 indicates the base of the machine which base carries a pedestal 11 to which is pivoted at12 a table support 13. Secured to the table support 13 is a guide 14 provided with a way 15 in which travels the flattened upper end of a threaded rod 16 passing through a correspondingly threaded gear wheel 17 carried on a bracket 18. The gear wheel 17 meshes with the second gear 19 operated by a crank arm 20 to raise and lower the rod 16 and thus tilt the table support 13 on its pivot 12. Slidingly mounted in the table support 13 is a table 21. The table 21 is provided with a rack 22 (Fig. 7) engaging with a pinion 23 for sliding the table in the table support. The pinion 23 is operated by a hand wheel 24. Pivotally mounted on the table 21 by means of a stud 25 is a block 26 provided with a segmental rack 27 engaging with a worm wheel 28 operated by a hand Wheel 29. Mounted in the block 26 is a sleeve 30 carrying on its forward the stem 59 of thelast support.

end the jaw slide 31. Arranged in the aw slide 31 are a'pair of jaws 32, each of whichis'provided with a: ca1n:slot 33 en- :gaging with. a pin 34 lILthG'OPPOSItBJQW. Each of the aws 1s=also provided with a second cam: slot 35 having a t'orward extension'36. These-slots 35 engage'with a pin 37 carried in'the.jaw1slide31. Jaws 32 are engaged by :links '381pivotedto a cross bar 39 carried on a rod'40' extending through thesleeve. 30, and provlded at :its

rear end with a canrcylinderfi41 {loosely mounted between a collar #42; and 1 disc 43.

The cam cylinder 41, lSiPIfOV ldQd with a cam slot44, as best shown in Fig.;,6, hi h-engages with a ping45 carried in/an arm-46 attached to theblock 26. The cylinder 41 is operatedbymeans of a handle 47. At-

1 tached to the jaws 32a-re blades 48-assh0wn in Figs. 3 and 4 or box ,toe molds'49 as shown inFig. 5. These blades and molds are interchangeable by means of bolts 50. In order to rotate the sleeve 30,=the.said

sleeve isprovided withv collar 51 carrying a segmental rack 52 engaging with a worm operated by a'hand wheel 54.

Sli'dingly mounted on the base 10 is a standard 58 inwh-ich is slidingly mounted This stem is connected by means of yokes 60 and 61 with a treadle 62 for vertically reciprocating said stem. In order to adjust the height 'to which thelast is" raised, a rod63 provided with right and left hand threads, is preferably interposed between the yokes 60 and 61. In order to move the standard 58 toward and away from the table 21, the said standard is attached to a threaded rod 64 connected with a hand wheel 65. The upper end of the stem 59 has pivotally secured to it at a last supporting member 71 provided with a pin 72 adapted to slide in a suitable opening in the heel of the last 73. This last supporting member 71 is adapted to be operated on the pivot 70 by means of a cam 74 engaging with a curved arm 75 carried on the said member 71. The upper end of the stem 59 has also secured to it a vertically movable block 76 to which is pivoted at 77 an arm 78 carrying on its upper end an adjustable toe support 79 adapted to engage with the toe of the last 73.

The operation of the machine is as tollows: 'llhe last is removed from the sup port 71 and the shoe placed thereon after which the shoe and last together are placed ,Ly means of the treadle 62.

in position in the machine. The toe of the shoe is held firmly against the support 7 9 by operating the cam 74. The last may be adjusted to any suitable angle by means of the pivoted arm 7 8. The jaws are adjusted to the shoe by means of the crank 20 and the hand wheels 29 and '54. The last may be adjusted towards and away from the jaws by means of the hand wheel 65 or the jaws may be adjusted to the last by means of the hand wheel 24. After the proper adjustments are made if it is desired to enclose the toe, the last is first raised by depressing the treadle 62 and the operating rod 40 forced forward by means of the'cam e1. Thefirst movement of the rod 40 will cause the jaws 32 to move bodily forward, thus bringing the blades as against the toe of the shoe. As soon as the pin 37 has moved out of the extension 36 of the slots 35, the forward movement of the jaws will be arrested and the jaws forced to move pivotally together by the combined action of the cam slots 33 and 35 thus enclosing the toe. In order to press the inturned flange of the upper, the jaws are first closed and the last 73 carrying the shoe then forced upwardly In order to form a box toe, the blades 48 are replaced by the box toe mold 4 9, the operation being the same as when enclosing the toe.

Having fully described my invention, what I claimas new and desire to secure by Letters Patent of the United States is:

1. In a shoe machine, the combination with a support, of a member mounted thereon and capable of both pivotal and sliding movement, clamping jaws, a longitudinal movable shaft for actuating said jaws, and a manually operated cam drum mounted on said shaft to move the same longitudinally.

2. In a shoe machine, the combination witha support, of a member mounted theremounted on said shaft to move the jaws longitudinally.

'3. In a shoe machine, the combination with a support, of a, member mounted thereon and capable of both pivotal and sliding movement, a sleeve rotatably mounted in said member, clamping jaws, a longitudinally movable shaft passing through said sleeve, and means for rotating said shaft to operate said jaws.

4:. In a shoe 'machine, the combination with a support, of a member mounted thereon and capable of both pivotal and sliding movement, a sleeve rotatably mounted in said member, clamping jaws, a longitudinally movable shaft passing through said sleeve, and a manually operated cam drum carried by said shaft for actuating said jaws.

5.111 a shoe machine, the combination with a base, of a support plvotally mounted on said base and provided with aguide way, a threaded rod carrying said base and having a flattened end engaging with the guide way in said support, an internally threaded gear engaging with said rod to move the same longitudinally to turn said support on its pivot, a table mounted on the support, and clamping jaws slidingly carried on said table.

In testimony whereof, I have hereunto set my hand and affixed my seal.
